FRANK m. DUNN AND ROLLIE G. KROH, or NEWTON, owa. i

Be fit known that we, FRANK M. DUNN and Roman Gr. Knorncitizens of theUnited States, residing at'Newton, in the county of Jasper and State ofOhio, have invented new and useful Improvements in Cold- Storage-VVellSystems, of which the follow; ing aspecification. g

This invention is ;an improved well cold storage system for utilizingthe comparatively low temperature of a, well to keep food and otherpe'rishable products. in acool and sanitary condition and forfstoringthe same for use, the invention consisting in the construction,combination and. arrangement of devices hereinafterde'scribedandclaimed.

One object of our invention is to provide an improved apparatus of thiskind which I 1 is partly an elevation and partly a vertical sectionalview of a well cold storage system constructed inaccordance with ourinvention and in use in connection with an ordinary dug well. Fig. 2 isa similar View on a plane at right angles to that of Fig. 1. Figs. 3 and4 are detail views. Fig- 5 is a detail sectional view of a portion ofone of the guides and of one wall of the well house walls.

In accordance with our invention we provide a suitable base or platform1 which is placed over the mouth of the well and on which is a wellhouse 2 of suitable size,

shape, and construction. The well house is here shown as of oblongrectangular form and as provided with a gable roof 3. The

- front wall 4 of the well house is provided with a door 5 which ishinged at one side as at 6. On the inner side of the door, at its upperend is a keeper 7 A locking bolt 8 is arranged on the inner side of thefront 7 wall 4, above the door opening, and is normally projected bymeans of a spring 9 for COLD STORAGE-WELL SYSTEM.

engagement with the keeper 7. This latch bolt has a knob 10 foroperating it to release the keeper and door. Ventilating openings 11 arein the upper portions of the frontand rear walls and are provided withscreens 12 to exclude insects.

I A shaft 13 extends transversely across the well house at asuitableelevated point and at a suitable distance from its rear end, ismounted in bearings14 in the side walls of the well house and isprovided at its center with a sprocket wheel 15 and at one end with acrank 16. Said shaft is also provided with a ratchet wheel 17 which isnormally engaged by a gravitating pawl 18, the said pawl beingpivotedas-at 19 and a stop 20 being provided to limit the extent of movement ofthe pawl, A s orocket wheel 21 has its axle mounted in a forked hanger22 which depends from the ridge of the roof, the said wheel beingmounted substantially midway between the front and rear sides of thewell'house.

A safe or cage 23 is arranged for vertical movement in the well and ismoimted between a pair of vertical guides 24. These guides are inpractice preferably made of iron pipe, such as gas or water pipe and areprovided at their upper ends with elbows 25 and which have screw plugs26 at their upper ends. Bolts 26 engage the screw plugs and cooperatetherewith for connecting the said elbows to the side walls of the wellhouse. The lower ends of said guides are provided with elbows 27 and areconnected together by a cross bar 28, which is also preferably a pieceof pipe or tubing. The guides are also connected to the guide walls ofthe well house and suitably spaced therefrom, by means of bolts 30, theheads of the bolts being on the outer sides of the walls of the wellhouse and thebolts being provided with adjusting and clamping nuts 31 onthe outer sides of said walls, washers 32 being interposed between thewalls and the said nuts. These bolts and the screw studs enable theguides to be adjusted so that they may be arranged in exactperpendicular position.-

The safe or cage 23 has semi-circular clips 33 on its side walls at itslower end which engage the guides and is also provided on its sidewalls, at its top, with two pairs of lugs 34 which engage opposite sidesof the guides and which clear the bolts that connect the guides to theside walls so that the safe or cage is permitted to be freely raised andlowered. The cage is preferably made of sheet metal or other materialwhich admits of the cage being readily cleaned and kept in sanitarycondition and the safe or cage has a hinged front door 35 which isprovided with screened ventilating openings 36 and also has a knob 37. Astaple shaped keeper 38 projects from the front wall of the safe or cageto pass through a slot 39 in the free side of the door and a pin 40 isconnected to the door by a chain and may be engaged with said keeper tosecure the door when in closed position.

A chain 41 is connected to the top of the safe or cage and passesoverthe sprocket wheels 21 and 15, a counterweight 42 being attached tothe other end of said chain." The safe or cage may be readily raised andlowered by turning the shaft 13, as will be understood, and when inraised position is held in such position by the engagement of the pawlwith the sprocket wheel 17.

On the upper side of the cage is a tappet 43 which when the safe israised from the well and in the well house engages the knob of thelocking bolt and releases the latter from the keeper of the well housedoor, thus adapting the door of the well house to be readily opened toafford access to the safe. When the well house door is closed and thesafe or cage lowered in the well to keep the articles therein cool, thespring actuated bolt reengages the keeper of the well house door Copiesof this patent may be obtained for five cents each, by addressing theCommissioner of.

Washington, D.- C.

' In apparatus of the class described a structure at the mouth of awell, tubular guides extending down into the well and having elbows attheir .upper ends, screw plugs in the upper ends of the elbows',boltsextending through the walls of the structure and engaging said screwplugs, adjusting bolts also connectin'gthe, tubular guidesto the wallsof the structure, a cross b'ar connecting the lower ends of the guides,a safe arranged be tween and slidably connected to the guides forvertical movement, and means to raise and lower the safe.

In testimony whereof we afiix our signatures in presence of twowitnesses.
